OPEN ACCESS. The genus Monocorophium Bousfield and Hoover, 1997 is represented by 4 species in European waters: M. acherusicum (Costa, 1853), M. insidiosum (Crawford, 1937), M. sextonae (Crawford, 1937) and M. uenoi (Stephenson, 1932) (Lincoln 1979; Bousfield and Hoover 1997; Faasse 2014). These species are native from European waters, except M. uenoi native from Japan, and M. sextonae which may have a South-West Pacific origin for some authors (Goulletquer et al. 2002). M. uenoi was recorded in The Netherlands in 2013 (Faasse 2014) – the first report from European waters. The present paper deals with M. uenoi record from the French Atlantic coast, which precedes the previous record. Materials and methods Study area (Figure 1) Arcachon Bay is a 180 km² macrotidal coastal lagoon, connected to the Atlantic Ocean by a narrow channel and receives freshwater from Leyre River. The lagoon is characterized by large intertidal flats (115 km²) (Plus et al. 2010). Farms rearing the Pacific oyster Magallana gigas (Thunberg, 1793) occupy the deeper intertidal.

Bidasoa Estuary represents the border between France and Spain in the South East of the Bay of Biscay. It is a short estuary with some feral oyster reefs. No shellfish or commercial port are present. Water temperature ranged from 12 to 22 °C and salinity ranged from 13 to 35 ppt with an average of 17 ± 4 °C and 31 ± 5 (mean ± SD) respectively. Environmental data (temperature and salinity) for both Arcachon Bay and Bidasoa Estuary were provided by the SOMLIT (Sevice d’Observation en Milieu LITtoral, a French coastal monitoring network: http://somlit. epoc.u-bordeaux1.fr/fr/). Material examined Monocorophium uenoi was collected during benthic surveys, in Arcachon Bay and Bidasoa Estuary (Figure 1, Table 1). Specimens were examined with a Nikon SMZ 1500 stereomicroscope and a Nikon Eclipse E400 microscope with up to 112,5 and 400x magnifications (and transmitted light) respectively.

Changes in vegetation structure can alter the physical habitat structure, thermal environment, and food available to arthropods, which play an important role in the structure and functioning of Arctic ecosystems. Not only do they provide key ecosystem services such as pollination and nutrient cycling, they are an essential food source for migratory birds. In this study I examined the relationships between the abundance, diversity, and community composition of arthropods and the height and cover of several shrub species across a tundra-shrub gradient in northwestern Alaska. To characterize nestling diet of common passerines that occupy this gradient, I used next-generation sequencing of fecal matter. Willow cover was strongly and consistently associated with abundance and biomass of arthropods and significant shifts in arthropod community composition and diversity.

Jess R. Bone Abstract Climate change induced sea level rise and increase in associated storms is impacting the coastal zone worldwide. Lagoons are a transitional ecosystem on the coast that are threatened with habitat loss due to ingress of seawater, though conversely this also represents an opportunity for lagoon habitat creation. It is important to quantify the spatio-temporal trends of macrozoobenthic communities and abiotic factors to determine the ecological health of lagoon sites. Such information will ensure optimal and adaptive management of these rare and protected ecosystems. This thesis examines the spatial distribution of macrozoobenthic assemblages and the abiotic and biotic factors that may determine their abundance, richness and distribution at tidally restricted urban lagoon at Poole Park on the south coast of England. The macrozoobenthic assemblages were sampled using a suction corer during a spatially comprehensive survey in November 2017, in addition to aquatic and sediment variables such as salinity, temperature, organic matter content and silt content. Species richness and density were significantly lower in areas of high organic matter and silt content, indicative of hostile conditions.
